Setion Four - S Registers

Your modem has 35 registers, designated S0 through

S30, S37, S90, S108, and S109. Table 4-1 shows the regis-

ters, their functions, and their default values. Some registers

can have their values changed by commands. If you use a

command to change a register value, the command remains

in effect until you turn off or reset your modem. Your modem

then reverts to the operating characteristics specified in its

non-volatile memory. Refer to Section 3 for information on

how to use the AT commands to manipulate the S registers.
